Shouldn't "Du" mangling be officially mentioned in ABI docs by now?
Yes, but no one submitted a PR to actually get the docs updated. I have now.

Correct. I stopped using the vendor extended type mangling before submitting the changes for inclusion in gcc 9.

(i.e. in https://itanium-cxx-abi.github.io/cxx-abi/abi.html)
(Might not be the right place to ask, sorry!)
I saw it used in many binaries out there, and had a hard time finding a proper definition, until this thread.
